Description
Es ist bekannt, die Schaltraumwandungen von elektrischen Stromunterbrechern, wie z. B. Löschrohrableitern, Druckgasschaltern, Schmelzsicherungen oder auch Gleichrichtern, zwecks Löschung oder Beblasung des Lichtbogens durch Gase ganz oder teilweise aus Stoffen aufzubauen, die unter Einwirkung des Lichtbogens Gase abgeben. Für den Aufbau solcher Schaltraumwandungen wird vor allem Hartgummi verwendet, dem gegebenenfalls noch ίο bestimmte Füllstoffe, die die Gasentwicklung unter der Einwirkung des Lichtbogens fördern oder beeinflussen, zugegeben sein können. Es ist aber auch bereits bekannt, solche Schaltraum wandungen aus Kunstharzen in Form von Harnstofformaldehydkondensationsprodukten, die Stickstoff als chemischen Bestandteil enthalten, herzustellen. Diese Stoffe sollen gegenüber Hartgummi den Vorteil haben, daß sich unter dem Einfluß des Lichtbogens kein grafitierter Kohlenstoff bilden kann, der die Oberflächenisolation der Wandung herabsetzen könnte.It is known that the control room walls of electrical circuit breakers, such as. B. Extinguishing pipe arresters, Compressed gas switches, fuses or rectifiers, for the purpose of extinguishing or Blowing out the arc with gases to build up entirely or partially from substances that are exposed to the action of the arc give off gases. For the construction of such switch room walls, above all Hard rubber is used, which may also contain ίο certain fillers that reduce gas development promote or influence the effect of the arc, may be added. It is also already known, such switch room walls made of synthetic resins in the form of urea-formaldehyde condensation products, which contain nitrogen as a chemical component. These substances are said to have the advantage over hard rubber have that no graphitized carbon can form under the influence of the arc, which the Could reduce surface insulation of the wall.
Gemäß der Erfindung wird nun bei elektrischen Stromunterbrechern mit ganz oder teilweise aus gasabgebenden Stoffen bestehender Schaltraumas wandung diese Schaltraumwandung ganz oder zum Teil aus Superpolyamiden aufgebaut, die aus Diamin - Dicarbonsäurekondensationsprodukten oder Aminocarbonsäurekondensationsprodukten bestehen. According to the invention, electrical circuit breakers are now completely or partially off Gas-emitting substances of existing Schaltraumas wall this switching room wall entirely or to Partly built up from super polyamides, which from diamine - dicarboxylic acid condensation products or Aminocarboxylic acid condensation products exist.
Diese Stoffe zeichnen sich gegenüber den bekannten Kunstharzen z. B. auf Harnstofformaldehydbasis durch wesentlich größere mechanische Festigkeit und bessere Wärmebeständigkeit aus.These substances stand out from the known synthetic resins such. B. based on urea formaldehyde by significantly greater mechanical strength and better heat resistance.
Es ist auch möglich, die Superpolyamide in Verbindung oder Mischung mit anderen geeigneten Stoffen zu verwenden. So hat sich beispielsweise zur Herstellung von Schaltraumwandungen für Löschrohrableiter bereits eine synthetische Hartgummimischung auf Basis eines Butadienmischpolymerisates, die ein solches Superpolyamid enthielt, gut bewährt. Während nämlich ein Hartgummi auf Basis von synthetischem Kautschuk im Gegensatz zu natürlichem Hartgummi unter Einwirkung des Lichtbogens keine wesentliche Gasentwicklung zeigt, wird diese Gasentwicklung des synthetischen Hartgummis durch die Beigabe von Superpolyamiden in ausreichendem Maße gesteigert. It is also possible to use the superpolyamides in combination or a mixture with other suitable ones Fabrics to use. For example, for the production of switch room walls for Extinguishing pipe arrester already a synthetic hard rubber mixture based on a butadiene copolymer, which contained such a superpolyamide has proven its worth. While namely a hard rubber based on synthetic rubber in contrast to natural hard rubber under action of the arc does not show any significant evolution of gas, this evolution of gas becomes the synthetic one Hard rubbers increased sufficiently by adding super polyamides.
Ein solcher synthetischer Hartgummi mit einem Füllstoff in Form von Superpolyamiden zeichnet sich dabei gegenüber synthetischen Hartgummimischungen mit anderen, für natürlichen Hartgummi üblichen Füllstoffen durch bessere mechanische Festigkeit aus.Such a synthetic hard rubber with a filler in the form of superpolyamides draws compared to synthetic hard rubber mixtures with others, for natural hard rubber conventional fillers are characterized by better mechanical strength.
Eine Hartgummimischung für die Zwecke der Erfindung kann je nach Bedarf verschiedene Mengen an Superpolyamiden enthalten. Diese Mengen werden sich zweckmäßig z. B. in den Grenzen zwischen 20 und 200 Teilen auf ioo Teile synthetischen Kautschuk halten. Nachstehend wird ein Beispiel für eine derartige Mischung" gegeben:A hard rubber compound for the purpose of the invention can be in various amounts as required contained in superpolyamides. These amounts are appropriate z. B. in the boundaries between Hold 20 and 200 parts to 100 parts synthetic rubber. The following is an example for such a mixture "given:
100 Teile eines Mischpolymerisates von Butadien mit Styrol,
50 Teile eines linearen Diamin-Dicarbonsäurekondensationsproduktes, 100 parts of a copolymer of butadiene with styrene,
50 parts of a linear diamine-dicarboxylic acid condensation product,
30 Teile Schwefel.30 parts of sulfur.
Dazu können gegebenenfalls noch Hartgummistaub bis zu 100 Teilen und organische Beschleuniger bis zu 2 Teilen zugesetzt werden.In addition, hard rubber dust up to 100 parts and organic accelerators can optionally be added up to 2 parts can be added.
In der Zeichnung ist beispielsweise ein Löschrohrableiter mit einem Schaltraum gemäß der Erfindung dargestellt. Die Schaltraumwandung besteht aus einem zylindrischen Rohr 1, das z. B. aus einem linearen Superpolyamid oder aber aus einer synthetischen Hartgummimischung auf Basis eines Butadienmischpolymerisates besteht, die ein Superpolyamid als Füllstoff enthält. Dieses Rohr trägt zugleich die Elektroden 2, 3 und die Befestigungsarmaturen 4, 5. In the drawing, for example, is a pipe arrester shown with a control room according to the invention. The control room wall exists from a cylindrical tube 1, the z. B. from a linear super polyamide or from a synthetic hard rubber mixture based on a butadiene copolymer, which is a super polyamide contains as a filler. This tube also carries the electrodes 2, 3 and the fastening fittings 4, 5.
